4.5.5 Programming the Device

You are ready to program your device. Select Programmer>Program to program the

entire device (i.e., all of the program memory, Configuration bits, etc.).

If you want to program selectively (e.g., part of program memory, only Configuration

bits), select Programmer>Settings

to open the Programmer Settings dialog. Click the

Memory Ranges tab (see Table 4-1 and Section 7.5.1 “Memory Ranges Tab”) and

select the options for programming. Areas that are grayed out are not available on the

device. Click OK. Then, select Programmer>Program

to program the device. The

memory area corresponding to the checked boxes will be programmed.

After MPLAB PM3 programs a device, it automatically performs a verify operation and

displays any errors found. An additional verify operation may be done via selecting

Programmer>Verify

4.6 VERIFYING THE PROGRAMMING

Click Programmer>Verify to verify that the programming on the device matches the

program memory, Configuration bits, ID locations, EEPROM and calibration memory

values in MPLAB IDE and in the Settings dialog and Configuration Bits dialog.

If there are more errors than expected and those errors claim that the bad data is all

zeros (0000), the socket module might not be seated properly. Remove and reseat the

socket module. It is always a good practice to insert a known blank device and do a

Blank Check whenever the socket module is changed.
